IMPROVEMENT IN GUIDES FOR SAWING-MACHINES.

Specification forming part of Letters Patent No. 183,889, dated October31, 1876; application filed September 16, 1876.

To all whom it may concern:

Be it known that we, CORNELIUS R. BLAU- VELT, of Newark, in the countyof Essex and State of New Jersey, and PETER V. V. SAGE, of East Orange,in the county of Essex and State of New Jersey, have invented a new anduseful Improvement in Guides for Sawing- Machines, of which thefollowing is a specification:

Figurel is a top view of our improved device. Fig. 2 is a cross-sectionof the same, taken through the line 00.70, Fig. 1. Fig. 3 is across-section of the same, taken through the line y y, Fig. 1.

Similar letters of reference indicate corresponding parts.

The object of this invention is to furnish an improved device forholding work While being mitered or beveled, which shall be soconstructed that it may be quickly and firmly secured to the table, andreadily detached when not required for use, which may be readilyadjusted for any thickness of Wood, and to any style of table, whichwill allow the table to remain horizontal, so that there will be noextra strain upon the saw, which may be readily adjusted to bevel thewood at any desired angle, and which will greatly lessen the labor ofsawing.

The invention consists in the combination of the bar, the adjustable armand bar, the rigid arm, and the hinged bar andits clamping-screw withthebed-plate,forsecuringthe device to the saw-table; and in thecombination of the hinged and slotted plate or frame, the curved andslotted hinged arm and its clamping-screw, the sliding plate and itsT-bars, and clamp with the bed-plate and its rigid arm, as hereinafterfully described.

A is the bed plate of the device, to one end of which is pivoted acurved bar, B, the inner edge of which is rabbeted to fit upon the edgeof the saw-table. The other end of the bed-plate A is slotted to receivethe arm Q, to the outer end of which is pivoted a rabbeted bar, D,similar to the bar B.

The arm 0 is secured in place adjustably by a clamping-screw, c. Forattachment to a square table the bars B D should be made straight.

To the rear edge of the bed-plate A is attached, or upon it is formed,anarm, E, to the outer end of which is hinged a bar, F, which projectsforward to pass beneath the top of the saw-table, and which is drawnagainst the said table-top to secure the device in place by a set-screw,f, which passes through a hole in the arm E, and screws into the saidbar F.

To the forward edge of the bed-plate A is hinged the lower edge of aplate or frame,'G, to the middle part of the upper edge of which ishinged the end of a curved bar, H. The bar H is slotted longitudinallyto receive the screw h, by which it is secured to the arm E, so that theplate or frame G may be readily adjusted at any desired angle to giveany desired bevel to the wood.

In the plate or frame G are formed two longitudinal slots to receive theT- shaped bars I, attached to the under side of the plate J, upon whichthe wood is placed to be beveled.

To one end of the plate J is hinged a jaw, K, which is held down toclamp the wood to the said plate J by a set-screw, k, which passesthrough the said jaw and screws into the said plate J. The forward endof the jaw K is made wide to give it a firm hold upon the wood.

With this construction the wood is fed forward to the saw by sliding theplate J upon the plate or frame G.

Having thus described our invention, we claim as new and desire tosecure by Letters Patent- 1. The combination of the bar B, theadjustable arm 0 and bar D, the arm E, and the hinged bar F and itsclamping-screw f with the bed-plate A, for securing the device to thesaw-table, substantiallyas herein shown and described.

2. The combination of the hinged and slotted plate or frame G, thecurved and slotted hinged arm Hand its clamping-screw h, the slidingplate J and its T- shaped bars I, and clamp K and set-screw k with thebed-plate A and its arm E, substantially as herein shown and described.
